We hear… that the couple has tapped Boston-area planner Bryan Rafanelli to coordinate the wedding, which is expected to take place under a tent at Astor Courts, a 3,500-acre private estate in Rhinebeck, New York. So we think… that Chelsea and Marc's wedding will be preppy yet undeniably grand—if Rafanelli's previous work is any indicator. He's planned everything from rustic lakeside celebrations to sexy ballroom weddings with dramatic light displays, crystal chandeliers, and abundant florals. Plus, Bryan is no stranger to high-profile events: He planned one of several inauguration celebrations for President Obama, and according to New York Magazine he also produced several fundraisers for Hillary Clinton's Senate campaign. Basically, we expect that in Bryan's hands it will be a stylish, memorable event (hopefully) tempered by an appropriate amount of dignity and restraint.

We hear… that the Clinton/Mezvinsky rehearsal dinner alone will rival the style and budget of an average New York wedding. According to several media outlets, the festivities will be held at Grasmere, another private estate in the Hudson Valley, and the Terrapin Restaurant, one of Rhinebeck's most upscale dining establishments, will be doing the catering. So we think… that the restaurant's signature dish of horseradish-encrusted ahi tuna with miso aioli will be on the menu (the entrée fits both Chelsea's vegetarian-but-fish-is-okay diet and President Clinton's requirements—he can't eat dairy).

We hear… that Oscar de la Renta and Vera Wang are the names being whispered as possible designers of Chelsea's dress. Oscar is already a Clinton family favorite, having designed inauguration gowns for Hillary during her husband's presidency, as well as the outfit she wore when she was sworn in as secretary of state. He also designed the dress for the 2008 wedding of Chelsea's fellow former first daughter Jenna Bush. But an inside source tells us that Chelsea and her mother have visited the Vera Wang offices several times back in February for dress fittings. When contacted, Vera Wang didn't care to comment. So we think… that this one is a toss up. Oscar de la Renta's clean, classic aesthetic matches the bride's tailored, structured, and often-conservative style, but it may well be Vera Wang, who will likely have to eschew her recent affinity for deconstructed, Avant-garde looks to create a personalized number for Chelsea (see Vera's M.O. last year when she designed Ivanka Trump's wedding gown).

We hear… that Jeff Leatham, artistic director of the Four Seasons George V Hotel in Paris, who currently has an office in New York, will create the floral arrangements for the event. Jeff's claims to fame include Eva Longoria's wedding and his reality show, Flowers Uncut, which aired on TLC last fall. Jeff is known for his luxe, architectural style and tends to favor bright pinks, purples, and all-white palettes. So we think… that Jeff will create clean, asymmetrical arrangements for Chelsea, featuring massive white calla lilies and white (or purple) orchids, perhaps with accents of yellow, which is rumored to be Secretary Clinton's favorite color.

We hear… that Norwood, NJ-based Vali Entertainment will be providing the music for the event, according to The New York Times. The company's talent has performed at several political events and, according to the jukebox on their site, has perfected everything from current Top 40s hits to Big Band swing. So we think… that the Clintons' overall strategy—to keep this "Chelsea's wedding"—will allow for some more current tunes to be played (think Estelle's "American Boy" for the cocktail hour and the Black Eyed Peas' "I Gotta Feeling" to get everyone dancing at the reception). Still, classics will most certainly be played: "The Way You Look Tonight" for the bride's dance with her saxophone-playing father? "New York, New York" for the last dance? And how great if the band played a modernized rendition of Joni Mitchell's "Chelsea Morning," the song the bride was named for? Another nostalgic possibility: Fleetwood Mac's "Don't Stop" (poli-wonks will recall that this was President Clinton's 1992 campaign song).

We hear… that The Paper Trail, a paper-goods store in Rhinebeck, is putting together 310 gift bags that will include Rhinebeck Farmers' Market paper calendars and woodcut honeybee prints in orange totes. (Source: The Daily Beast). As a welcome gift, the Wall Street Journal says that guests will be greeted with a bottle of wine from the nearby—and appropriately named—Clinton Vineyards. So we think… that in addition to all these lavish material goodies it would be bad form for the couple and the Clintons not to "give back" to one or several of their favorite charities. The bride is currently studying health policy and management at Columbia University's Mailman School of Public Health, and has been very involved with the Haiti earthquake relief effort through her family's own charity, the Clinton Fund, and Project HOPE.
